Board assembly with chemical vapor deposition diamond (CVDD) windows for thermal transport

摘要

A method and apparatus for conducting heat away from a semiconductor die are disclosed. A board assembly is disclosed that includes a first circuit board having an opening extending through the first circuit board. A Chemical Vapor Deposition Diamond (CVDD) window extends within the opening. A layer of thermally conductive paste extends over the CVDD window. A semiconductor die extends over the layer of thermally conductive paste such that a hot-spot on the semiconductor die overlies the CVDD window.
